Abstract

The invention discloses a flexible active power control system for a photovoltaic power station and a feeder removal algorithm method for the flexible active power control system. The system comprises a flexible active power control device, a remote function module, a scheduling data network and an AGC (automatic generation control) system in the photovoltaic power station, wherein the remote function module, the scheduling data network and the AGC system communicates with the flexible active power control device. The method comprises the following steps: a communication module of the flexible active power control device communicates with the remote function module, the scheduling data network and the AGC system in the photovoltaic power station to acquire data of the photovoltaic power station, receive a planned generation active power value, transmitted by scheduling, of the photovoltaic power station and simultaneously forward the planned value to the AGC system. By a feeder selection algorithm, a high-quality generation resource can be maximally reserved, generation loss can be reduced, more benefits are created for an owner of the power station, and contributions are made to the environmental protection business.

Description

technical field

[0001] The invention relates to the field of automatic control of new energy power generation, in particular to a flexible active power control system of a photovoltaic power station and a feeder cutting algorithm method thereof. Background technique

[0002] In recent years, in order to promote the use of renewable energy and clean energy, the country has introduced many policies to support and encourage the development of new energy industries. A large number of photovoltaic power stations, wind farms and other new energy power stations have been put into operation and connected to the grid system. Due to the randomness, intermittency and volatility of photovoltaic power plants, dispatching cannot control the power generation of the power plant well. Only relying on AGC (Automatic Generation Control) adjustment can no longer meet the needs of "power generation tracking load". The safe and stable operation of the power grid has brought greater impact and cha...
